Asparagus tea processing technology
1. Technological process:
Raw material picking-spreading-drum killing-air cooling-hot air secondary killing-rolling-rolling-spreading, cooling-hot air drying-finished product-packaging
2. Main points of operation:
1. Raw material picking: length 3~3.5cm, cutting length requires high uniformity.
2. spread out: concentrate the picked raw materials and spread them out in a room with good ventilation and convection conditions. generally, bamboo mats or plastic films are used as floor mats to dry the surface moisture in a natural state.
3. Drum kill: put the raw materials on the drum machine for head killing, and the drum temperature is controlled at 85-95 ℃.
4. Cool air: set up blowing facilities at the discharge port, the wind is continuous under the material, after the cutting is over, continue to blow 3~5min.
5. Hot air secondary killing: put the air-cooled raw materials on the sieve plate of the hot air baking machine, put in 2000250 ℃ hot air, bake and shake until the raw materials are 780% dry, and complete the second green killing.
6. Knead and twist: in the bamboo plate, hold the raw material after moderate heat dissipation with both hands, push and knead forward, use wrist strength for appropriate pressure, knead until there is a slight stem sap overflow and moisturization.
7. Billet, cool: the wet billet after kneading is shaken in time and evenly spread out in the bamboo plate, so that it continues to emit hot air and part of moisture in the natural state, so that the moisture in the stem is evenly dispersed and easy to dry.
8. Hot air drying: it is consistent with the second green operation of hot air, and can be stopped when it is crushed by hand.
9. Finished product: the water content of the finished product is 810%, and the yield is 1820%.
10. Packaging: immediately packed at a cooling temperature of about 45 ℃ to prevent the finished product from absorbing moisture and easy to cause mildew.

What if the new leaves of Camellia oleifera fall off
I bought a pot of tea plum from the south, which has been growing well for three years, but from this spring, red dots appeared on the new leaves, and soon the leaves fell off, and the effect of carbendazim was not good. What is the cause of this, please? How should prevention and treatment be carried out? A: from the situation you have described, combined with the leaves of the clip, it is inferred that it is caused by net cake disease after the new leaves are harmed by mites. The disease occurs more seriously from April to June and from September to October. It mainly occurs when it has been fully developed

General Junfeng "Zhaoping Maojian" tea
The raw materials of Zhaoping maojian are collected from the alpine tea garden in Zhaoping brain Mountain. The tea garden was designated as a nature reserve by the forestry authorities in the 1970s, with overlapping peaks, undulating hills, dense forests, towering ancient trees, vertical and horizontal streams, and pure and fresh air. Zhaoping maojian selects high-quality fresh leaves of improved varieties of tea, refined by traditional tea-making technology combined with modern processing technology, with tight appearance, white hairs, green and glossy color, long-lasting fragrance, clear and bright soup color and taste.
